Yhep, without a micro controller this would be a lot of wiring. You'd need a bunch of 4017's and then you'd need to rig a series of AND gates like Aaron said to trigger them correctly. I've done this with two 4017's to count to 16 and even that was kinda long to do.

You could modify the counter circuit on this website to have two digits (instructions are on the page) and then set up a system of AND gates to trigger a reset when the output of the display is showing 60, but that seems like a lot of work. Program a PIC to count to 60 and reset.

Im unable to find a schematic that will only count to 60 probly because it will need to be programed. there are some 2 digit 0-99 counters
